for a while the fastest street supra in the world was a 9.51 and he had 950+rwhp and the head had never been off the car. the skyline engine can handle 600 horsepower not rwhp but crank power before it becomes unstable. that doesnt mean that it cant hold 1300 hp for a few seconds while going down the track. but certainly not a daily driven car.
the inline engines is better for making torque over a V style engine. and also lower in the rev band. also i know three supras that i race with here in st louis that has 750rwhp on stock internals but stock HG. just blot ons. the other two only have 500 and 450 rwhp but they to are on stock internals.
the skyline engine i have read about a few years ago and a nissan engineer for NISMO said that the engine can handle 600HP on the stock block before added bracing would be needed. the only downfall i see about the inline six is the fact of the 7M series that has the worst cooling system. there is no bleeding screw at the top of the block and the thermostat is at the top of the engine so the car must either be jacked up 2-3ft or on a very steep hil. and even then its almost impossible to get all the air pockets out of the heater core. the longer block makes for a longer nose but also a longer wheel base making the car more stable at high speeds. right where the supra is at home.
